CONFLICT OF INTEREST CODE FOR SENATORS

17. (1) Neither a Senator, nor a family member, shall accept, directly or indirectly, any gift or other benefit, except compensation authorized by law, that could reasonably be considered to relate to the Senator’s position.

Exception

(2) A Senator, and a family member, may, however, accept gifts or other benefits received as a normal expression of courtesy or protocol, or within the customary standards of hospitality that normally accompany the Senator’s position.
